perf powerpc: Add support for PERF_SAMPLE_WEIGHT_STRUCT
Add arch specific arch_evsel__set_sample_weight() to set the new
sample type for powerpc.
Add arch specific arch_perf_parse_sample_weight() to store the
sample->weight values depending on the sample type applied.
if the new sample type (PERF_SAMPLE_WEIGHT_STRUCT) is applied,
store only the lower 32 bits to sample->weight. If sample type
is 'PERF_SAMPLE_WEIGHT', store the full 64-bit to sample->weight.
